Answer:
D. BGP
Explanation:
In order to exchange routing information with another AS (Autonomous Systems) only, exterior routers use an exterior routing protocol, like BGP (Border Gateway Protocol) or EGP (Exterior Routing Protocol).
BGP is an application-layer protocol in the TCP/IP suite, that uses a well-known TCP port (179) in order to deliver information reliably.
It is important to note that in order to exchange routing data within his own AS, the router uses an interior routing protocol, like OSPF.
Your wireless network has been breached and it seems as though the attacker has modified a portion of your data that is used with a stream cipher. This was used to expose wirelessly-encrypted data. What type of attack is this?
Answer: IV attack
Explanation:
IV attack is stand for the initialization vector attack that are used over the wireless network an it is used as the encrypted packet during the process of transmission. An initialization vector attack basically attempts for exploits for exposing the encrypted information.
According to the question, the IV attack is basically used with the stream cipher for exposing the information wirelessly.
The initialization vector is one of the arbitrary number that are used in the for of secret key in the system and it helps in prevent the duplicate character in ciperhtext.

192.168.1.96/28 and 192.168.1.64 /27
Explanation:
In computer networking, subnetting is a way of sharing up a network into several more networks. It's importance includes improving routing effectiveness, enhancing security on the network and better managment control. subnetting is acheived by slicing IP address, in the case given in the question, Subnet 192.168.1.64 /27 with 5 bits allocated for the host and will only be able to hold 32 addresses, Subnet 192.168.1.96/28 on the other hand has 4 bits for the host addresses and as such will be able to hold 16 addresses.
In computer science, what are two names that are used to describe data structures organized by association
Answer:
Answer to the following question are,
Association list TablesExplanation:
Because these are the two associations data structures.
Association List: are referred to that data type which contains the pair of the key and item in the Java Programming Language and Python Programming Language, it is called a dictionary data type.Tables or Hash Tables: are referred to that data type which converts the keys into the integer value.Final answer:
In computer science, 'associative arrays' and 'maps' are two data structures organized by key-value associations, which enable efficient retrieval of data.
Explanation:
In computer science, two names that are often used to describe data structures organized by association are associative arrays and maps. An associative array (also known as a dictionary or a map) is a data structure that pairs unique keys with corresponding values.
This allows for efficient data retrieval based on those keys. Similarly, a map is a collection of key-value pairs where each key is unique and is used to store and retrieve data. Both associative arrays and maps are highly useful for situations where quick lookups of associated data are necessary.

You're responsible for technical support at a High School. You're concerned about students with some technical knowledge reconfiguring machines, either maliciously or not. You have already made sure Windows is secure and the students' login has the minimum necessary privileges. What else should you do to prevent students from re-configuring the school lab computers?
Answer:
setup a password for the BIOS
Explanation:
The BIOS refers to Basic Input/Output System. When a BIOS password is set, it will enforce autentication whenever an attempt is made to login at startup. Remember that the computer's microprocessor uses the BIOS to bootup, and it is also responsible for managing information flow between the OS and other devices, therefore very sensitive settings are maintained here, setting up a password will further ensure that that students do not intentionally recomfigure the computers in the school laboratory.

A salesperson in your organization spends most of her time traveling between customer sites.After a customer visit, she must complete various managerial tasks, such as updating yourorganization's order database.Because she rarely comes back to your home office, she usually accesses the network from hernotebook computer using Wi-Fi access provided by hotels, restaurants, and airports.Many of these locations provide unencrypted public Wi-Fi access, and you are concerned thatsensitive data could be exposed. To remedy this situation, you decide to configure her notebookto use a VPN when accessing the home network over an open wireless connection.Which key steps should you take when implementing this configuration? (Select two.)a. Configure the VPN connection to use MS-CHAPv2.b. Configure the browser to send HTTPS requests through the VPN connection.c. Configure the VPN connection to use IPsec.d. Configure the browser to send HTTPS requests directly to the Wi-Fi network withoutgoing through the VPN connection.e. Configure the VPN connection to use PPTP.
Answer: b. configure the browser to send HTTPS requests through the VPN connection
e. configure the VPN connection to use PPTP
Explanation:
b. sending the HTTPS requests directly to the WiFi network will bypass the VPN which will make the sensitive data vulnerable, hence, defeating the reason for making use of the VPN.
e. the salesperson accesses the WiFi using her notebook computer, which is most likely going to be running on a windows operating system, OS. The VPN connection type for windows OS is usually PPTP (it will be provided in the subscription details by the VPN being used). However, Mac OS does not support the PPTP. In such cases, the VPN being used will also provide the information (usually IKEv2).

Laura manages DLP for a large company where some employees have COPE and some have BYOD. What DLP issue could these devices present?
Answer:
For the COPE device, there won't be a lot of risks, because this type of model is very secure and trustworthy. The device belongs to the company and only the corporative use is allowed. The company owns maximum control on the information managed by the device. Some Blackberry devices were only COPE designed.
For the BYOD device, is the opposite, because this type of model is very unsecure since it doesn't count with the security barriers like the COPE model does, leading to the user losing critical information or getting hacked by installing malware. Even though it is a cheaper alternative for a lot of companies, it's far away from beign the most recommendable in terms of security, productivity and privacy.
which command should you enter to configure a single port to discard inferior bpdus 200-125?
Answer:
spanning-tree portfast bpduguard
Explanation:
spanning- tree protocol (STP) is a layer 2 protocol in the OSI model. It is automatically configured in a switch to prevent continual looping of BPDUs, to avoid traffic congestion. The fastport bpduguard is only applicable in non-trunking access in a switch. It is more secure to configure the fastport mode in switch port connected directly to a node, because there are still bpdus transfer in a switch to switch connection.
BPDUs Guard ensures that inferior bpdus are blocked, allowing STP to shut an access port in this regard.

Write a static method named printTwoDigit that accepts an integer n as a parameter and that prints a series of n randomly generated numbers. The method should use Math.random() to select numbers in the range of 10 to 19 inclusive where each number is equally likely to be chosen. After displaying each number that was produced, the method should indicate whether the number 13 was ever selected ("we saw a 13!") or not ("no 13 was seen."). You may assume that the value of n passed is at least 0.
Answer: Following code is in java language :-
import java.lang.Math;
public class
{
public static void main(String args[])
{
printTwoDigit(6); //6 is the number of random numbers to be generated
}
public static void printTwoDigit(int n)
{
int i = 0;
int arr[]=new int[n]; //will declare a array of n size
int flag=0;
while(i<n)
{
arr[i] = 10 + (int)(Math.random()*10); //produce random number each time
System.out.println(arr[i]+" "); //print all random numbers
i++;
}
for(i=0;i<n;i++)
{
if(arr[i]==13) //to check if 13 was generated
{
flag=1;
break;
}
}
if(flag==1)
System.out.println("we saw a 13"); //this line is mentioned in question
else
System.out.println("no 13 was seen"); //this line is mentioned in question
}
}

we saw a 13
Explanation:
In the above code, an array is declared with size n(which is passed as an argument to the function) to store the list of all random number produced.Random() is multiplied by 10 so that it can produce a number 10 numbers starting from 0 and then 10 is added to the generated number so that minimum value generated would be 10.All numbers generated are printed to console n times and stored in arr.After that arr is checked for value 13 so it can print whether 13 was produced or not.Final answer:
The printTwoDigit method generates n random numbers between 10 and 19 using Math.random(), checks if the number 13 appears, and prints a corresponding message.
Explanation:
The method printTwoDigit generates and prints a series of random numbers between 10 and 19, using the Math.random() function. To generate numbers specifically in the range of 10 to 19, we can multiply the result of Math.random() by 10 and then add 10 to shift the range. After generating each number, the method checks if the number 13 was generated and prints a message accordingly. If at least one instance of the number 13 appears during the sequence, the message "we saw a 13!" is displayed; otherwise, the message "no 13 was seen." is shown.
Here is an example implementation of the method:
public static void printTwoDigit(int n) {
boolean saw13 = false;
for(int i = 0; i < n; i++) {
int randomNum = (int)(Math.random() * 10) + 10;
System.out.print(randomNum + " ");
if(randomNum == 13) {
saw13 = true;
}
}
System.out.println();
if(saw13) {
System.out.println("we saw a 13!");
} else {
System.out.println("no 13 was seen.");
}
}
